Question

Instructions. For each question, show all work leading to an answer and simplify as much as reasonably possible. 1. A 3.00-kg block starts from rest at the top of a ramp having an inclination of 30.0°. The block slides a distance of 2.00 m down the ramp in 1.50 s. Neglect air resistance. (a) Find the magnitude of the blocks constant acceleration. (b) Find the coefficient of kinetic frictioti between block and ramp. 2. A small, flat cushion of mass m is released from rest at a top corner of a building having height h. A the side of the building exerts a horizontally forward force of constant magnitude wind blowing along B on the cushion as it drops. The air exerts no vertical force. (a) Show that the path of the cushion is a straight line. (b) Docs the cushion fall with constant velocity? Explain.

    Please answer this question below with all work shown. A 2kg block is placed at rest on a frictionless incline that is angled 25o. It is released and slides 30.0 cm (distance s) along the incline before reaching the floor. The floor exerts a kinetic friction force f of 1 N on the block. How far does the block slide (distance x) on the flat section (different from s) before it stops?

    7.7. Please answer all the questions and show your work. A 4.20-kg block is set into motion up an inclined plane with an initial speed of v_1 = 7.60 m/s (see figure below). The block comes to rest after traveling d = 3.00 m along the plane, which is inclined at an angle of theta = 30.0 degree to the horizontal. For this motion, determine the change in the block's kinetic energy. J For this motion, determine the change in...
